3d printing device

Abstract

The invention discloses a novel 3D printing device, comprising: a frame; a printing box, which is arranged on the frame; a three-dimensional substrate worktable is arranged on the bottom of the printing box, and the three-dimensional substrate workbench also includes: a support frame ; a support plate, which is detachably arranged in the support frame, and a plurality of through holes are arranged in a row on the support plate; a plurality of sliding columns, which are parallel to each other and reciprocally slidable, are arranged in the plurality of through holes in one-to-one correspondence; A plurality of polygonal sheets; an elastic body; and a 3D printing head, which is arranged in the printing box, and the 3D printing head is arranged facing the basic face shape I'. A new type of 3D printing device provided by the present invention can quickly and individually generate the 3D printed facial support body of the bionic mask, without the need to print the facial support body of the bionic mask separately, which is convenient and quick, with small errors, and can further improve the bionic mask. user experience.

Description

Technical field [0001] The present invention relates to 3D printing technology, and more particularly, to a 3D printing apparatus. Background technique [0002] 3D printing is a rapid prototyping technology, it is a three-dimensional digital model as a base, a metal, plastic, photosensitive resin molding material is molded by way of technology object layer by layer printing, belonging additive manufacturing. Currently based on fused deposition modeling (FDM: Fused Deposition Modeling) 3D printer principle of simple structure, variety of suitable materials, equipment and supplies and low cost, it has become one of the highest penetration rate of 3D printer. [0003] Existing bionic mask, for comfort, realistic, generally want to pour on the face mode operation, the operating time of up to a few hours, the user experience is very poor wear; while the use of 3D printing technology to print silicone material bionic mask, since silicone material elasticity, hardness is not high, it is...

AI Technical Summary

Problems solved by technology

[0003] For the existing bionic masks, in order to wear them comfortably and realistically, it is generally necessary to perform an inversion operation on the human face. The operation time is as long as several hours, and the user experience is very poor. It has elasticity and low hardness. It is necessary to print the support body before printing the bionic mask to meet the support requirements of bionic mask printing. However, in view of the fact that the current 3D printing technology generally only has one nozzle, the model (bionic mask) and the support body can only be Use the same material to print, which makes it very troublesome to remove the support after printing. If the model itself is accidentally injured when removing the support, the entire print will be scrapped

Not only time-consuming and laborious, but also the printing effect is not good
